PATENT OFFICE.

The innovations relate to an engine with two cylinders. The drawing shows a section through the axis of one of the two cylinders. . The upper part of the cylinder has been left out and only the lower cover B is shown, in which the ignition device with the associated safety and distribution organs is located. The piston y is movable in the cylinder. C is the ignition piston, D is the loading piston with forced axis rotation, E is the safety valve, G respectively. g the compression hammer, K the explosion space, L the reservoir for the explosion mass. In the same the reddening distribution piston L ¹ moves with the six-wing screw L ⁰ at the lower end. M is the regulating slide for distributing the explosion mass.

The six-wing distribution screw L ⁰ is pressed onto the bottom of the distribution cylinder by a spiral spring. With each revolution of the working shaft of the motor, a wing of the screw L ⁰ moves past the distribution opening L ⁶ and thus brings an amount of explosive mass corresponding to the power output to be achieved in front of the opening of the distribution slide M, after which it is withdrawn, the mass into the channel L ⁶ . falls. The slide M makes a larger or smaller path, depending on the setting of its mechanism of movement, and moves faster or slower, so that a regulation of the absolute horsepower can thereby be achieved.

When the loading piston D is advanced, the explosive mass falls from the channel L ^e into a cavity R of this piston, which is provided at its end with a leather cuff D ² and moves in a bore E ^{s of} the cylinder cover. The piston receives its movement at D ¹ from the regulator shaft; it is rotated in its advance by sliding in a Schraubennuth Traverse D ^B 90 ^0, swept, whereby the cavity R down and 'falls in their located Explösionsmasse in the explosion chamber K. · The bore E ⁵ is closed by a safety valve E and this must first be lifted in order to allow the piston D to enter the space K. The piston D passes through a through hole E ⁴ provided in E. The valve E is moved by lever arms E ¹ , which are attached to the shaft E ² and receive their movement by an eccentric mounted on the regulator shaft.

In contrast to other arrangements, the purpose of the safety valve here is only the temporary admission of explosive mass and the temporary closure. of the gases produced by the explosion, but not the distribution of the explosive mass itself. On the lower part of E there is a spiral spring E ^a made of flat steel which, after piston D has retracted, returns the valve to its previous position. "Immediately afterwards the mass of the explosion is ignited.

This is done in the following way:

After the explosive material has entered the

Space K has been conveyed, it falls into the funnel S, where it is compressed by a hammer G. The latter is on the side

Claims (3)

a lower piston rod C2 and upper C3 in the cylinder cover B rotatably mounted about an axis X and receives its movement from a toothed wheel g2 wedged on X, which is set in rotation by a toothed sector g *, which in turn is moved by levers and articulated rods from the regulator shaft . The hammer G is especially valuable and necessary when using an explosive mass - called paleine - which is a kind of cellulose and can only be made to explode in a compact state. While the explosion is taking place, the hammer is in the position shown in full lines. The gases remaining after the explosion can escape through the channel g & with every stroke of the hammer G. The mass is ignited by the igniter C, which consists of a piston C1 and a piston. The same is moved up and down in a suitable manner from the regulator shaft. At \ there is a rectangular channel running across the cylinder-shaped housing, which serves to lead through an endless ignition belt. The latter is covered in certain interstices with small discs of fumed mercury and is passed through the canal in a suitable manner so that its surface is perpendicular to the axis of the cylinder. The upper end of C3 is shaped in such a way that when piston C warms up, a fuse is popped out of the fuse band; At the same time, the fuse is struck against the ignition surface T and the explosive mass in S is ignited. In the cylinder housing W, the piston C1 moves airtight, and the piston rod C2 is also guided in the lower cover V in an airtight manner. Above the piston C2, a discharge duct Hs is mounted in the housing W and such an He is mounted below the piston; the upper channel is in communication with the open air, while the lower one is closed by a tap H *. The cock H ^ is set in such a way that the gas escaping downwards around the flask can only partially escape through H4 when the mercury explodes, so that a kind of air cushion is formed below the flask, while above it the gas flows freely Hs can escape. Godfather ν τ claims: 1. In explosion engines, the arrangement that the explosive material is introduced into the explosion chamber by means of a spoon-like hollowed-out piston DR through a bore E ^{i of} the shut-off valve E and is compressed there by a rotatable hammer G , which closes the outlet duct for the explosion gases, before ignition takes place . 2. In connection with the arrangement claim i. an ignition device, consisting of a piston C ¹ , which with an upper extension C ³ detaches a squib from an ignition strip passing across it and strikes against the stop surface T of the ignition channel, causing the ignition. 3. In connection with the ignition device marked under 2. the arrangement of one gas escape channel each above and below the ignition piston in the wall of the cylinder, in such a way that the upper one the gases discharged into the open, while by closing off the lower channel by means of a regulating valve a counter pressure can be generated on the piston in the manner of an air cushion to reduce the kickback if the primer ignites.
